Games usually automatically adjust degree of rotation depending on a car. The thing is that every mid to high end wheels has 900 degrees or more, there is no reason to go lower than that. There aren't really good sim racing wheels with degree of rotation lower than 900.

Hey mate, I use Thrustmaster TX. Unfortunately, as far as I know gamepads in Project Cars are inferior compared to the wheels, so they are not very competitive in terms of lap times/tire wear. If you want a cheap and decent wheel, check for Logitech DFGT/G27 or Thrustmaster T150!
